Deep Cycle batteries are designed to be deeply discharged and recharged hundreds of times. They are designed and built differently than automotive starting batteries. They use more lead, heavier plates and other proprietary materials that enable them to deliver more power and capacity over many life cycles. Deep Cycle batteries are used in many applications including; Boats, RVs, Solar and Wind power, Electric Vehicles, Electric Golf Cars, Floor Cleaning machines, Aerial Work Platforms and many more.
